GEARING.

Specification of Letters Patent.

Patented Junev 7, 1921.

Application flied september 26, 191s. serial No. 255,798.

To all whom t 'may concern:

Be it known that I, JULiUs H. KINTZELE, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a new and useful Gearing, of which the following is a specification. Y

This invention relates to gearing` An object of the invention is to provide a novel and eiiicient gearing for machines requiring a reverse movement, comprising mechanism for operating the machine and including means for reversing theV movement of the machine or driven part thereof while the A driving mechanism or gearing continues to operate in the same direction.

In the drawing- Figure 1 is a view illustrating my invention in connection with a portionv of a washing machine."

Fig. 2 is a view showing the support for the pinions included in the train of gearing for driving the driven mechanism.

Fig. 3 is a view illustrating the face of the cam device for swinging the pinions to opposite sides of the large gear constituting a part ofthe driven mechanism and by which the Idriven mechanism is operated alternately in opposite directions. v

As shown the drive shaft 1 is arranged to be rotated constantly in one direction. A worm 2 on the drive shaft meshes with a worm gear 3 mounted loosely on a shaft 4 supported at right angles to the shaft 1. A clutch member 5 on the shaft 4 is movable into and out of engagement with the hub of the worm gear 3 so that said gear may be locked in connection with the shaft 4; to rotate the shaft, or released in order to leave the shaft stationary while the worm gear continues to rotate. The clutch device is of familiar construction and the specific details thereof are unimportant, since it is obvious that any appropriate clutch device may be employed for this purpose.

rThe portion of the gearing just described is inclosed within a case comprising a support 6 providedrwith an end wall 7 having a bearing for one end ofthe shaft 4. The opposite end of the shaft 4; is supported within a sleeve 8 extending froina swinging arm 9 into an appropriate bearing in the case 6. n

A pinion 10 which is fast on the shaft 4 meshes with an intermediate pinion 11 on a supporting stud 12 carried by the swinging arm 9. The pinion 11 meshes with a pinion i 13 on the supporting shaft 14 carried by the swinging arm 9.

In the specific form of .they invention shown the mechanism to be operated includes a gear wheel 15, the teethof which are engageable on opposite sides. If desired the gear wheel 1'5 may be of the construction shown in which the teeth are iii the form of radial pins in connectionwithtwo rings constituting a part of the wheel, although it is 4obvious that the teeth of the gear wheel may be otherwise arranged if desired. As shown the teeth of the wheel 15 are not continuous throughout the circumference of the wheel, but there is a space at one side ment with the last tooth at either side of the cam block 16 the end of the shaft 14 engages the cam 17 on that side of the cam block. Due to the shape of the cam and the` fact that the pinion 18 remains in engagement with the gear 15, the pinion 18 is moved around to the opposite side of the gear 15. vSince the pinion 18 Vcontinues to revolve in the same direction and becomes thus engaged with the opposite side of the gear 15, the latter will be turned in the opposite direction from its former movement, and this operation is repeated once during each revolution of the large gear 15.

The arm 9 is within a housing and extent of lateral movement thereof is limited so that the pinion 18 will be positively retained in engagement with the gear 15. As shown the extent through which the arm may move may be varied. The stops or abutments for limiting extent of swinging movement of the arm are in the form of screws 19 (Fig 2) which may be adjusted to dierent positions to form stops for the swinging arm.

The arm also operates against a supporting portion 20 of the housing which constitutes a strong support to prevent the parts from becoming loose or displaced.

The same driving mechanism may be emwringer. A part of such gearingis' shown including a worm gear 2l mounted on a shaft 22" adapted; to operate the wringer mechanism. .v

I do not restrict myself to uness'ential details but what I claim and vdesirev to fsecure by Letters' Patent, is

l. Gearing of the character describedv comprising a gear wheel, a support, a shaft journaled'for rotation in saidsuppoirt at right-angles tothe axiso'i1 the gear'wheel,

means for rotating saidshait, a pinion atil tached to said shaft', an arm having one end pivoted on said 'support 'and arranged to' swing on its pivot from one position'to` `an' other, a support against which the opposite end of said arm slides" in` its" movements, means rlimitingy swinging moveiientof" said arm, apinionsupported bysai'd arm me'shl' ing with the pinionf'ii sai'dshajft', ars'haft" supported by Asaid arm, a pinion' onfy said last-named shaft driven by,v ,said second! named pinion, and an additionai pinion `on said last-namedshaft driven by said lastnamed pinion meshing with said` gear wheel.V
